I’m trying to save my Nvidia GPU’s BIOS to a file, but I keep getting this error.
My computer is the ASUS TUF Gaming FX505DD laptop.
GPU I’m trying to save: NVIDIA GeForce GTX 1050 Mobile 3 GB
I’m trying to create a Windows gaming virtual machine on Linux, following this tutorial.
If anyone has the ROM file for this GPU, or has a solution that allows me to dump the rom file, that would be amazing. Thank you.

Try with NVFlash from our downloads section. Any luck?
-
#3
Did you actually select the NVIDIA GPU from the pull-down menu?
If you select the AMD iGPU that comes with your system, GPU-Z will fail
So does mine: Heavy Metal umlaut Y = $FF = -1 = buffer over/underrun?

Which IGP is that?

Cezanne, ID 1638
GPUCapsViewer reads the BIOS version at least.

Could you create a new thread, so I can keep track of this?

#7
I’ve already tried NVFlash with no luck. And I’ve definitely selected my dedicated Nvidia GPU. Anything else I can do? Thanks.

Did you ever solve this? I am wondering if my SIV utility can dump it, to check look at the Menu->Machine->GPU VBIOS Status panel and if there seems to be some Raw Image Data press [ GPU-0 ] to dump it.

#9
red-ray’s SIV utility seems to have worked, it has saved the file, although I haven’t tested it yet. Thanks!

#10
Red-Ray,
worked on mine.
Had the same problem
Bios reading not supported on this device.
I used your latest and dumped!
THank you!
Do you know how to calculate NVCAP?
I need for MacOS

I am pleased to see SIV was able to dump the VBIOSes, given the code SIV uses to implement this am surprised GPUZ is unable to do this and wonder why not.
I had never heard of NVCAPs so after a quick Google found https://github.com/1Revenger1/NVCAP-Calculator and assume you could use this. I guess it’s MacOS only and as SIV is Windows only am not inclined to add NVCAP reporting to SIV.

Your app, It sure worked. I was glad.
But to no avail.
The IGPU takes over in laptops. The variables are not hacked well.
For desktops there’s flexibility.
Thank you it sure saved scrounging the Net.

Is there a way of dumping AMD Cezanne 5750GE iGPU Bios somehow? I’d need that for proxmox virtualization.

I dont have any [ GPU ] buttons. Can you send step by step screenshots.

What do you see? Post a screen shot.
It’s changed to Menu->Machine->GPU Detail->GPU VBIOS Status with later SIV releases.

I dont have that option.

#18
It’s only there for NVidia GPUs.
Idk why, but unable to read
I expect the RX 560 is in power saving mode and powered down, further I expect [PCI Bus] won’t show it either.

whenever i try to save my bios with GPU-Z it says «Bios reading not supported on this device» is there any way to get around this? oh and my card is an ATI X1300 mobility radeon.
-
#2
You have a mobile GPU, meaning integrated. The graphics BIOS is part of the main system BIOS, hence why it cant be extracted.
-
#3
dang, oh well thanks for the help, weird thing is I’ve taken my laptop apart and i could have sworn i saw the card in there separately from the processors or anything else for that matter.
-
#4
WOA Alex, your kinda wrong on that one.
X1300 Mobility is a seperate card entirely.
The X1150, X1200, X1250 are integrated.
Your cards external read/write pins have been cut to prevent improper flashing by ATI.
-

Didnt realise it was a separate card sorry. Thanks for the input Flyoride.

Hello everybody. Is there any solution to this issue? I have an MSI 4870 512mb radeon and receive the same message, just wanted mod fan settings to higher value, since it’s a little bit hot on defaults. Need your help, where do I look for those pins?
-
#7
Well the problem was in Win7, I have changed OS to MS windows Xp SP2 and successfully dumped 4870’s bios using GPU-Z. Good luck all!

Atti, which BIOS version are you using with your Acer?
-
#10
The laptop’s BIOS is v1.15 and the Radeon’s BIOS is VER011.022.002.002.033474

that’s curious didn’t know it was possible to prevent reading an BIOS. Although can understand writing/flashing.

Thank you very much!
I didn’t think the vido BIOS is a part of the system BIOS 
But… how can I write the modified video rom back?

But… how can I write the modified video rom back?
If your really confident you can change the Video BIOS how you want it without changing the length then it should just be a case of replacing the Insyde EFI module in the v1.15 BIOS and flashing the whole BIOS. Well, that’s the theory anyway 
I don’t know anything about the Video BIOS but have played with Insyde. If your happy to take the risk let me know and I’ll try to help you out.
EDIT (3-Jan) : I guess from a lack of an answer that your not happy to take the risk. Probably wise since there is a chance of bricking.
If anyone is curious I successfully changed the Video BIOS in my old EFI main BIOS with a newer version extracted from a newer EFI main BIOS. So it can be done.
Before
After
You might wonder why I didn’t just update the whole BIOS to the new one! Well the main BIOS I’m using fixes a few things that a multitude of later BIOS updates from HP didn’t. Also it seems that either HP silently removed or broke the esata boot capability in later BIOS versions. So although my old main BIOS is a little buggy it’s good enough for what I want but the later versions aren’t, at least for me that is. Of course other people might find the newer BIOS’s better.

Can you help?
Thanks!

Okay, I’ll have a look at putting something together. If you haven’t already, make a backup of the BIOS your using now. You should be able to boot to DOS and use flashit utility which comes with the BIOS update archive.
Flashit.exe backup.fd /G
where backup.fd is the name used for the backup file that will created. The Insyde EFI BIOS tends to come with a built in crisis recovery although the notebook manufacturers don’t seem to document this. It tends to work along the lines of…
- Placing the recovery file renamed to whatever is specific for the notebook being recovered on a medium such as a FAT formatted USB flash drive.
- Removing the battery power.
- Removing the AC adapter.
- Holding down a couple of keyboard buttons, for Acer fn + Esc seems quite common.
- Insert the AC adapter.
- Turn on using the power button.
- Once started up, release the keys held down and hopefully see the laptop shut down after a minute or two.
The hardest part is trying to work out what the BIOS file should be renamed to. You might be lucky and someone has already found it for you. Try to get your crisis recovery worked out before flashing. If it becomes unrecoverable by this method then you will need to find another way to reflash the BIOS chip. Beware, it seems the laptop manufactures would probably charge you for a new mainboard rather than trying to fix the BIOS chip. Work out all your options before hand if something should go wrong and then decide if you still want to go ahead.

Could I ask you guys one favor?
Try using RBE to extract your BIOS, even if you’re using a non-ATI card. Download RBE, run it and click «Acquire/flash…». In the upcoming window uncheck «Load into RBE» in the «Alternative BIOS extraction» box. Then click the «Acquire BIOS…» button and save your BIOS. Please note: This will work with 32-bit versions of windows only.
If you don’t mind attach the BIOS to a post in this thread and don’t forget to tell what kind of video card you have.

«BIOS Reading Not Supported» GPU Z error when trying to back up vBIOS. URGENT HELP needed due to bricked vbios!
I have an Asus Scar 15 with RTX 3080Ti, whose vbios got bricked while trying to flash GE76 175W vbios. Now I’m trying to get someone who owns the 3080ti variant to dump vBIOS, using GPU Z, but GPU Z says «BIOS reading not supported on this device». How do I solve this issue? And is there any alternate way of dumping vbios? Please help. I’m stuck at a mere 200mhz on the GPU, and the laptop is totally unusable.
